Letters Patent No; 92,637, dated July 13, 1869.

IMPROVED INSTRUMENT I OR CUTTING- PEGS FROM BOOTS, 8cc.

,The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, FRANK OsBoRNE, of South Hanson, in the county ot'Plymouth, and State of Massachusetts, have invented certain Improvementsinl-Instruments for ,Cutting Pegs from Boots and Shoes, of which thefollowingl is a full, clear, and exact description, reference being had'to the. accompanying drawings, making part oi' this speciii'cation, inwhich- Figure l is a perspective View of my improved instrument.

Figure 2 is a longitudinal section through the centre of the same.

Figure 3 is a transverse section, on the line :1; xot' fig. 2.

The device ordinarily used for cutting pegs from the interior ot' bootsand slices is objectionable, for the. following reasons, viz: Not beingsurrounded with a guard, its knife-edges are apt to b'e brought againstand inj ure the upper leather, and the form ot' thc port-ion of Vtheinstrument adjacent to the knife-edges is such, that it becomesextremely diiticult to sharpen them when dull and worn away, aml thewhole instrument soon becomes worthless, and is discarded for a new one.

My invention has for its object to remove, the above-mentioneddifficulties, and consists in a {nife made independently of andremovable at pleasure from the main portion ot' the instrument, by whichconstruction, when the cutting-edge is dull, the knife may bereadily.removed to be sharpened, and when worn away may be replaced by anew' one at a tritling cost.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in\\vhich I have carrie-d it out.

In the said drawings- A represents a circular metallic rod, provided atone end with a wooden handle, .15.

At vthe opposite eml of this rod is formed a screwthread, a, which litsinto a corresponding thread in the inner end of a metallic racket orplate, O,wbie11 is slotted out, for the reception of a metallic block,D, which is held in place therein, and is pressed tightly against a thinblade, E, )rovided with cutting-edges, l) c, on two of its oppositesides.

The outer extremity of the portion ot' the rod provided with ascrew-thread tits into a recess in the centre of the rear end ot theblock D, by whicli construe tion the knife-blade may be held immovablyin place, the slotted plate C serving as a frame or guard to enclose theknife-blade, and protect the upper from injury from its edges, b c.

On reference to tig. 2, it will be seen that the inclination of thesecutting-edges b c to the shank or rod is such, that in one positionofthe rod the edge b forms an acute angle therewith, to adapt it for usein cutting off the pegs projecting up into the interior of the boot orshoe at its shank and toe-portions, while, when the rod is turned over,the edge c makes an obtuse angle therewith, or inclines out therefrom,to adapt it for use in cutting oii` the pegs projecting up inside thesole at vand nea-r the heel.

O ltti'ms.

\Vhat 1 claim as my invention, and desire to secure by Letters Patent,is

An instrument tor cutting pegs from bootsor slices,-A provided with aremovable knife, E, substantially as described Y Also, the slottedsocket C,aud block D, inY combination with the knife E, and rod A, withits screw-thread a, operating substantially as described, for thepurpose set forth. i
